Salts of cefadroxil with an amino acid selected from the group consisting of L-lysine, L-arginine and acetylcysteine. Said salts are obtained by reacting an aqueous suspension of cefadroxil with an aqueous solution of an amino acid or its derivative, selected from the group consisting of L-lysine, L-arginine and acetylcysteine. To isolate the salt, the aqueous solution is submitted to lyophilization.
